SAV.

Application filed January 25, 1924, Serial This invention relates toimprovements in tree saws and its object is to provide a manuallyoperated saw adapted for Cutting down standing trees. Etlicieney andease of operation are objects obtainet. lilith the foregoing and otherobjects in view the invention Consists in the combination andarrangement of parts to be hereinafter fully described, pointed out inthe appended Claims and illustrated in the accompanying drawing whichforms a part of this application and in which- Fig. 1 is a plan view ofthe saw illustrating its application.

Fig. 2 is a view of Fig. 1 in side elevation.

Fig. 3 is a view at right angles to the left side of Fig. 2.

Like reference characters denote corresponding parts in both views.

The reference numeral 1 denotes a platform having downturned lateraledges 2 that serve to support the same, said platform being formed witha centrally disposed longitudinally extending opening 3. Arranged uponone end of the platform is an integral standard 4 formed with anelongated slot 5, said standard being formed with an integral extensionor shoe 6, disposed substantially at right angles to the aid standardand adapted to rest upon the ground, said shoe being provided with aplurality of teet-h or spurs 7 adapted to bite into the earth, saidspurs being curved rearwardly thus preventing the shoe from slip* pingor creeping in one direction after it has been located.

An upright 8 is formed with a diminished portion 9 adapted to lie flatagainst the standard 4 to support the same, said portion 9 being slottedlongitudinally, said slot being adapted to align with the slot in saidstandard so that an adjusting bolt 10 may Connect the slotted portionsof said members to secure them iu adjusted position. The uprightterminates at its lower end in a base 10a formed with a transverseperforation 10". By loosening the nut upon the bolt 10 the upright maybe adjusted relative to the standard; from the position shown in Fig. 2it may be raised.

A bar 11 carried by the upright 8, and disposed at right angles thereto,is provided with a fork 12 provided with teeth 13, said fork and teethbeing adapted to partially encirele and bite into the tree trunk 14 tosteady No. 688,425. Renewed September 13, 1926.

the saw during its operation. The bar 11 extends through an elongatedslotted head 15 carried by the stand 16, said slotted head servingtoguide and brace said bar 11, said stand being supported by a forkedbase 17 arranged upon the platform 1, the depending sides of which areconnected by the cross brace 1. The slot in the said head 15 permits thebar 11 to be adjusted relative to the said head as the saw is raised orlowered. Pivotally and slidably arranged upon the bar 11 is t-he roc-lrlever 18 made fast to and operating the outer frame 19 the ends of whichpivotally support and operate the saw blade frame 20 that carries thesaw blade 21, said blade frame 2O being slidably supported by a forli 22that is integral with and terminates the angular follower lever 23 thatslides in the transverse perforation 10b in the base 10a, the outer bentend of said follower lever being adapted for engagement by the operatorsleg whereby said lever, saw blade frame and connections may be movedforward or toward the tree to be, or being, eut.

In operation the operator may stand with one foot upon the shoe 6 andone leg` at about the ankle, engaging the bent outer end of the followerlever 23 to cause the saw blade to contact with the trunk of the tree14. lVith one hand he oseillates the rock lever 18 thus reciprocatingthe frames 19, -20 which cause the blade 21 to cut the tree trunk. Thelover 18 or the follower lever 23, or both, may be used to advance thesaw blade as the tree is cut. To raise the saw from the position shownin Fig. 2 the nut upon bolt 10 is loosened and the upright 8 raisedtogether with the follower lever, carried thereby, and the bar 11 whichis also carried by the upright 8. The fork 12 bearing against the treetrunk tends to prevent it from falling toward the saw when cut. 0fcourse the tree trunk diametrically opposite the saw blade` will bechipped or out with an ax in the usual manner previous to the start ofthe sawing operation. l

wWhat is claimed is t- 1. In a tree saw. a platform, an uprightsupported thereupon and adjustable relative thereto, tree engaging meanscarried by said upright, a rock lever carried by said means, a framecarried by said rook lever, a second frame carried by said first namedframe, a blade for said second frame, and supporting means for saidSecond traine slidably earried by said upright.

2. In a tree Saw, a platform, an upright supported thereupon andadjustable relative thereto. tree engaging ineans Carried by Saidupright? a rock lever Carried by said means, a traine Carried by saidrock lever, a Second traine Carried by said first named traine, a blade'for said second traine, and a follower lever slidably Carried by saidupright and operatively supporting` said second trarne.

3. ln a tree saw, a plattoriinV an upright supported thereupon andadjustable relative thereto, tree engaging means carried by Saidupright. a rock lever carried by said nleans, a traine carried by saidrock lever, a Second frame pivotally Carried by Said tiret named frame,a blade for said second frame, an

angular follower lever slidably Carried by said upright, and a forliintegral with said follower lever and operatively Supporting said secondtrame.

fl. In a. tree saw, a platform7 an upright supported thereupon andadjustable relative thereto, a bar Carried by said upright at rightangles thereto, a toothed fork terminating` said bar, a rock levertulerun'ied slidably upon Said bar, a trame carried by said rock lever,a second .traine pivotally carried by said tiret named frame, a blade'for Said Second traine, and a followerlever slidabiy carried by saidupright and operatively supporting' said second' frame.

ln testimony that l claiin the foregoing as my own I have hereto allixedmy signature.
